JDL-350 Mechanical Top Drive Drilling Rig

The mechanical top drive series drilling rigs are a self-developed water well drilling equipment that integrates both water and air drilling functions.
1. The power head features a mechanical transmission method.
2. The drilling machine is equipped with a 525 series manual transmission.
3. The power head moves a single stroke of 3500mm.
4. Power head hydraulic automatic opening and closing mechanism.

The mechanical top drive series drilling rigs are a self-developed water well drilling equipment that integrates both water and air drilling functions (National Invention Patent: ZL201510479602.4). They feature a car-mounted 525 transmission box, with sensitive and convenient gear shifting, doubling the transmission efficiency over hydraulic drives and reducing power consumption by 35%, making them more efficient and energy-saving. They solve the challenges of low drilling efficiency in soil layers, hard rock formations, and cobblestone layers with conventional rotary drills.

Drilling machine main features:

1. The drilling machine features a speed range of up to 27-901 rpm, with a high output torque of 10,500 N.m.
2. The drilling rig features a long-travel double-speed mechanism and a mechanical power head with a stroke of 3500MM, designed to enhance drilling efficiency and reduce the occurrence of drilling blockages and burning accidents.
3. The drilling rig uses a dual-acting oil pump for feeding oil. It uses a single pump for drilling and a combined flow of dual pumps for lowering the drill. It has low power loss and short auxiliary time.
4. Equipped with a caterpillar undercarriage, the leg cylinder stroke is 1.5m, enabling automatic loading onto trucks for easy relocation and transportation.
5. The drilling machine is equipped with预留 functional interfaces in the mechanical and hydraulic systems, allowing for the expansion of functions to meet the process requirements of different users.
